Hi, I just built my own system on Wednesday, And it is working fine except for the fact that whenever I try to play a game. What will happen is that it will load the game and then after playing for about 5 to 10 minutes the game will crash. After this if I try to load the game it will instantly crash. And sometimes after it crashes the screen turns all fuzzy and the computer will restart. I have no Idea what is causing this, but I have almost ruled out it being the RAM. (I took the sticks out one at a time (so there was always 2 sticks in) and the problem persisted, but I haven't been able to take out 2 sticks at a time yet.(So only 1 stick would be in.) Also I don't think it is the video card, because before I got the system running I let my friend use it and he ran games perfectly fine on it. I believe I have all the latest drivers as well. Also if it helps my OS is windows 7.
Motherboard: MSI PRO E
GPU: Powercolor 5770
RAM: OCZ Triple channel
Processor I7 920 @ stock
Oh also I don't believe it is overheating either because I checked my temps in Everest and they were all fine.
* After running memtest my RAM failed, so I'm just gonna RMA it.
The PSU is a corsair 650w HX series, So I seriously doubt that it is the PSU overheating. (Plus I felt it to check and it wasn't warm at all.) The CPU temp is always under 40 degrees C (according to Everest). The GPU is seated perfectly fine as well (I repositioned it like 6 times thinking that it was loose or poorly seated. It is also far away from everything else.). I think it was the RAM that was bad, and it caused corruption in the system, which caused the screen to appear.
